List verification and cleanup
Every address is classified before a send is spent: sendable, catch-all, invalid or unknown, with the reason. A send to a dead address doesn't just get lost — it damages the reputation of every send after it.

How it works
- 01The list is normalized and deduplicated: domains, aliases and variants of the same business.
- 02We check whether the domain accepts mail and the mailbox exists; catch-alls are marked as catch-all, never as valid.
- 03Everything is cross-checked against global suppression: anyone who opted out stays out, whatever list they arrive on.
- 04You get the list back with class, reason, and a suggested alternative channel for whatever email can't reach.
What you get
- Classified list with a reason per address
- Quality report: what share was unusable and why
- Companies and sole proprietors separated by verified ownership
- Alternative channel proposed for unreachable records
Who it is not for
We don't enrich lists with third-party personal data and we don't add contacts you didn't have. We clean what exists; we don't expand it.
